H5PHP technology helps the creativity of big carousel lottery activities

In today's digital era, interactive marketing activities are widely used in corporate marketing, among which large carousel lottery activities are often used to attract user attention and participation. Combining H5 and PHP technology can not only enhance the fun and real-time nature of the lottery, but also improve user participation and interactivity, bringing more opportunities for corporate brand marketing.

In this article, we will introduce how to use H5 and PHP technology to create a creative big wheel lottery event, and provide specific code examples.

1. Front-end design of lottery event

First of all, we need to design an attractive large carousel interface that allows users to draw prizes. We can use HTML, CSS and JavaScript to implement this part of the interface design. The following is a simple HTML structure example:

      
  
 
 开始抽奖 
   

2. Lottery back-end logic

Next, we need to implement the back-end PHP logic to handle the functionality of the lottery. We can use PHP to generate winning results, record user participation, etc. The following is a simple PHP code example:

 $winningPrize, 'participated' => $participated ); echo json_encode($result); ?>

3. Front-end and back-end interaction

Finally, we need to implement front-end and back-end interaction so that after the user clicks the lottery button, the front-end initiates a request to the back-end Get the winning results and display them to the user. The following is a simple JavaScript code example:

const spinBtn = document.querySelector('.spin-btn'); spinBtn.addEventListener('click', () => { fetch('handle.php', { method: 'POST', body: JSON.stringify({ userId: '123' }), headers: { 'Content-Type': 'application/json' } }) .then(response => response.json()) .then(data => { alert(`恭喜您获得${data.prize}`); if (data.participated) { spinBtn.disabled = true; } }) .catch(error => { console.error('抽奖失败：', error); }); });

Through the above code example, we can implement a simple technology based on H5 and PHP
